Four people have been arrested on suspicion of arson following a fire that continued for over 24 hours.
The fire at McGuinness Scrapyard on Longport Road started at 5.47pm on Saturday, March 5.
Crews from Newcastle, Sandyford, Stone, Hanley, Longton, Uttoxeter, Longnor, Ipstones, Loggerheads, Biddulph, a water carrier from Cheadle and the Targeted Response Vehicle from Hanley were called to the blaze.
Staffordshire Fire and Rescue Service station manager Dave Steele, who attended the incident, said: “This was a severe fire that involved a large amount of scrap metal.
“Luckily, no one was injured as a result of the incident which was started deliberately.
“The actions of the culprits may have diverted vital resources from other incidents as well as putting the lives of firefighters and members of the public at risk.
“Anti-social behaviour such as this can have long lasting consequences for those responsible, including a fine or even a prison sentence.
“Having a criminal record can impact on future career prospects of those involved.
“It may seem like a bit of fun but the possible repercussions are no laughing matter.”
The last crews left the scene at 8.22am on Monday, March 7.
Staffordshire Police arrested four people, who were released on bail pending further inquiries.
A police spokesman said they are still appealing for witnesses and anyone with any information is asked to ring 101 quoting incident 565 of March 5.
